Patent DE-4317627-A1 (DE)
Title: Valve for gas or liquid conduits and method for its manufacture
Inventor: SCHULZ HARALD
IPC: F16K41/00
Filed: 1993-05-27
Abstract: The invention relates to a valve for gas or liquid conduits, with a valve body and with a spindle guided in a sealing manner through a mounting in a valve top part and serving the purpose of actuating a shut-off member in the valve body. The proposal is to modernise old valves of this design by removing the stuffing boxes in the valve top parts, thereby also eliminating the pressure elements for the stuffing boxes. The area for receiving the stuffing boxes is to be modified in such a way that a modern bearing bush, which is to be manufactured, which has a bearing hole for the spindle with modern sealing elements, can be inserted there in a leaktight manner, thus giving a modern valve which is easy to operate with only a little reworking and hence with very little expense.

Patent DE-4405815-A1 (DE)
Title: Semiconductor device having an anode layer which has low-concentration regions formed by selective diffusion
Inventor: KIM HOHYUN
IPC: H01L21/331
Filed: 1994-02-23
Abstract: A semiconductor device is disclosed, by means of which a PN junction can be formed by selectively diffusing impurities of various types selectively through a layer, having a low concentration, which is partly formed by a contact on a substrate composed of layers with high and low concentration of the same type. The semiconductor device can form a well in a single layer, which well is wholly composed of impurities of low and high concentration because of selective diffusion of an impurity of the same type, while exploiting the property that impurities are diffused laterally to the same extent as in vertical depth. This semiconductor device is distinguished by low loss and fast reversal recovery capacity since accumulated carriers can be removed via an anode terminal by using the layer having low concentration. If the semiconductor is used for a discrete device, an anode is formed in a single layer by diffusion. The production process is therefore simple. If a single chip consists of a transistor and a diode, a fast reversal recovery capacity can be achieved with the diode according to the invention, without impairing the transistor, which is attributable to the simultaneous formation of the base and of the diode.

Patent DE-4426801-A1 (DE)
Inventor: KUNZE JOHANN-GEORG DIPL ING
IPC: G01P1/12
Filed: 1994-07-25
Abstract: From the acceleration signals of a test object under vibration load alternation (eg. LW1) are determined according to amplitude and duration of individual half-waves. The corresponding values are stored and after the end of the measuring procedure they are converted in such a way that they are allocated to classes with different amplitudes and/or durations. The information found in this way is represented on a data display device (Fig. 3, not shown). The selected limits of the classes both for the amplitude and for the duration can be changed in any way. The same occurs with the secondary load alternations as with the load alternations. Moreover, an impact detection and impact evaluation is provided, where particularly large load-alternation half-waves are detected and likewise represented according to amplitude and/or duration (Fig. 5, not shown). The variables found allow an observer to make statements about the forces acting on a test object exposed to vibrations. <IMAGE>

Patent WO-8401008-A1 (WO)
Title: Epicyclic gear
Inventor: SEEFLUTH U CHRISTIAN
IPC: F16H3/72
Filed: 1983-08-26
Abstract: The epicyclic gear comprises a driving member, a driven member and a control member of which the peripheral speed may be varied with respect to the driving and/or driven members. The teeth of the different members are continuously in mesh with a given reduction ratio which is determined between the teeth of the outer members and/or by at least one reduction stage inside the intermediary member. The intermediary member interconnects the outer members so that they rotate in the same direction. In order to control the rotation speed of the intermediary member without having to overcome a reaction moment, a chain (72-75) is arranged between the driving member (71) and the driven member (77) of which the axes are arranged on at least two different radial lines (81-84) of the central axis (70). The whole assembly is sized in such a way that, when the gear is loaded, at least one of the wheels (72, 75) is supported by a neighbouring wheel by means of a radial traction or pressure load. Thereby, the control member has hardly any reaction motion when no control or braking force acts on the control member.
Patent WO-9117433-A1 (WO)
Title: Electrochemical determination of oxygen concentration
Inventor: PREIDEL WALTER
IPC: A61B5/1473
Filed: 1990-07-10
Abstract: A process is disclosed for electrochemically determining the oxygen concentration, in particular of bodily fluids, by means of an oxygen sensor having a sensor electrode. An exact oxygen concentration can be obtained by impressing upon the sensor electrode a potential profile with several potential stages. The first potential stage covers a range between -0,5 and -1,2 V (first measuring potential), the second potential stage a range between -0,5 and 1,3 V (second measuring potential) and the third potential stage lies at about 0 V, in relation to an Ag/AgCl reference electrode. There is a potential difference equal to or higher than 50 mV between both measuring potentials and the length of stay at each of both measuring potentials lasts between 10 and 50 ms (measurement period). The current flowing at both measuring potentials is determined and integrated in time, the integration starting 5 to 30 ms after the beginning of the measurement period and lasting for 5 to 10 ms. The oxygen concentration is determined by calculating the difference between both integrals.
